There's a new type of hybrid predator stalking the prairies and forests of the North Eastern United States. It's called the Eastern Coyote but some also call the animals Coywolves because they're really not Coyotes at all - they're a new mongrel breed with a combination of coyote and wolf DNA with a bit of dog thrown in as well. Dr Javier Monzon has been studying Eastern Coyotes ever since he was confronted by one of the animals in the wild while hiking in New York state.
